Having committed the sacrilegious act of placing ones sac on a religious or holy object or image. Not to be confused with sacrilegious which refers to having committed sacrilege (i.e. that which is "grossly irreverent toward what is or is held to be sacred" as stated by dictionary.com)
"Putting his sac on the image of their holiest leader is certainly a sacreligious act."

"When I am being sacreligious it may or may not be sacrilegious....but it is certainly sacrilicious"
